How are we going to feed the growing population using the same amount of land that we have now?

    One idea to help with this problem is to build vertical farms — by making what are, in effect, multi-story greenhouses, we can take advantage of vertical space not usually used for food production. Not only that, but simply building residences taller and more tightly-spaced will free up land for food production as well.
